      Optimal intereye difference thresholds by optical coherence tomography in multiple sclerosis: An international study

      Objective To determine the optimal thresholds for intereye differences in retinal nerve fiber and ganglion cell + inner plexiform layer thicknesses for identifying unilateral optic nerve lesions in multiple sclerosis. Current international diagnostic criteria for multiple sclerosis do not include the optic nerve as a lesion site despite frequent involvement. Optical coherence tomography detects retinal thinning associated with optic nerve lesions. Methods In this multicenter international study at 11 sites, optical coherence tomography was measured for patients and healthy controls as part of the International Multiple Sclerosis Visual System Consortium. High‐ and low‐contrast acuity were also collected in a subset ...

      In vivo volumetric imaging by crosstalk-free full-field OCT

      Cellular resolution imaging of biological structures has always been a challenge due to strong scattering that limits the achievable transverse resolution or imaging penetration depth. Recently, a major advancement toward high-resolution and volumetric imaging was achieved by implementing a parallel detection (i.e., full field) into Fourier-domain optical coherence tomography. The drawback of using parallel detection is that scattered light can travel laterally and get mapped improperly at a camera creating optical crosstalk, which severely impairs the interpretation of subcellular images and limits its use in medical diagnostics. In this work, we demonstrate for what we believe is the first ...

      Optimization-based vessel segmentation pipeline for robust quantification of capillary networks in skin with optical coherence tomography angiography

      Optical coherence tomography angiography (OCTA) provides in-vivo images of microvascular perfusion in high resolution. For its application to basic and clinical research, an automatic and robust quantification of the capillary architecture is mandatory. Only this makes it possible to reliably analyze large amounts of image data, to establish biomarkers, and to monitor disease developments. However, due to its optical properties, OCTA images of skin often suffer from a poor signal-to-noise ratio and contain imaging artifacts. Previous work on automatic vessel segmentation in OCTA mostly focuses on retinal and cerebral vasculature. Its applicability to skin and, furthermore, its robustness against imaging ...

      High frequency optical coherence tomography assessment of homogenous neck coverage by intrasaccular devices predicts successful aneurysm occlusion

      Background High frequency optical coherence tomography (HF-OCT) is a novel intravascular imaging technology developed for use in the cerebral vasculature. We hypothesize that HF-OCT characterization of intrasaccular device neck coverage can prognosticate exclusion of the aneurysm from the circulation. Methods Bifurcation and sidewall aneurysms were made in six dogs. Seven aneurysms were treated with next generation intrasaccular devices (NGID) and four with traditional platinum coils. HF-OCT was performed to interrogate gaps in the neck coverage, coil herniation, or acute thrombus formation. Animals were re-imaged at 7, 30, 90, and 180  days following aneurysm embolization.

      Light scattering has become a common biomedical research tool, enabling diagnostic sensitivity to myriad tissue alterations associated with disease. Light–tissue interactions are particularly attractive for diagnostics due to the variety of contrast mechanisms that can be used, including spectral, angle-resolved, and Fourier-domain detection. Photonic diagnostic tools offer further benefits in that they are non-ionizing, non-invasive, and give real-time feedback. In this review, we summarize recent innovations in light-scattering technologies, with a focus on clinical achievements over the previous ten years.

Two clinical cases are presented on patients with a bilateral decrease of their visual acuity and alteration in chromatic perception.

As renal function declines, rates of major adverse cardiovascular events, cardiovascular and all-cause mortality increase. In addition to hypertension, increased arterial stiffness is characteristic of CKD, a marker of CVD risk, and an independent predictor of mortality in CKD patients.

Using morphological parameters obtained from OCT and IVUS, a new plaque vulnerability score will be established for more precise definition of the most vulnerable plaques that carry the greatest risk of rupture and subsequent detrimental clinical outcomes in the future.

    1. We are very pleased with the outcomes of this study, which are the culmination of hard work by 47 physicians across 18 collaborating hospitals...What is further encouraging is that this study was undertaken without key technological improvements that have since been launched commercially. We anticipate that future studies using the Real-time Targeting laser marking feature and our newly launched artificial intelligence software, Intelligent Real-time Image Segmentation, will improve upon these already very positive results. Working together with our commercial partner, Merit Medical, and many of the leading hospitals in the United States, we are ecstatic that this technology continues to have an important and beneficial impact for patients.

    2. We can’t use functional OCT/OCTA in the brain to look at neurovascular coupling at the cellular level because the brain is surrounded by the skull, and fine resolution isn’t possible...But we can use functional OCT/OCTA to examine the interactions between individual photoreceptors and their blood vessels in the retina, which is much more accessible in the eye.

    3. With the NSTIN plot, the temporal quadrant of the retinal nerve fiber layer is displayed in the center of the B-scan. This portion of the disc is crucial for everyday visual function, and identification of abnormal thinning in this region is essential for managing glaucoma.

    7. You can see right into the tooth,” said Dr. Daniel Fried, professor, University of California, San Francisco School of Dentistry. “The enamel looks almost like an ice cube...Many lesions in the mouth have been re-mineralized and...no longer need inter­vention,” said Fried. “Dentists have trouble telling the difference between active and arrested lesions; this new technology has the potential of differentiating them.

    8. OCT [already] has changed the practice of ophthalmol­ogy...It’s been very successful for retinal imaging...and it’s also very promising for dentistry...If the dentist doesn’t know if [a lesion] is active or arrested,” said Fried, “with OCT, you can actually see the lesion struc­ture, how deep it is and if it has a definitive surface zone suggesting that remineralization has occurred.
